Gamma Cyclodextrin Analysis Service | Pharmaceutical Excipient
MtoZ Biolabs provides Gamma Cyclodextrin Analysis Service to deliver precise identification, quantification, and quality evaluation of gamma-cyclodextrin (γ-CD), a cyclic oligosaccharide composed of eight glucose units connected by α-1,4-glycosidic bonds. γ-CD is produced by the enzymatic conversion of starch using cyclodextrin glucosyltransferase. Its unique cavity structure enables it to encapsulate non-polar compounds, forming inclusion complexes that enhance the stability, solubility, and bioavailability of active ingredients.

As a versatile pharmaceutical excipient, γ-CD plays an essential role in modern formulation design. It improves the dissolution of hydrophobic drugs, stabilizes volatile compounds, and supports controlled-release delivery systems. Leveraging advanced analytical technologies and extensive excipient research experience, MtoZ Biolabs’ Gamma Cyclodextrin Analysis Service ensures accurate structural confirmation, purity verification, and quality control for both research and industrial applications.

MtoZ Biolabs offers a complete suite of analytical methods for the physicochemical and quality evaluation of gamma-cyclodextrin. Each procedure is conducted under validated conditions to ensure accuracy, reproducibility, and compliance with international standards.
● Identification
High-performance liquid chromatography (HPLC) and Fourier-transform infrared spectroscopy (FTIR) are used to confirm the identity of γ-CD. The retention times and infrared absorption peaks are compared with certified standards to verify structural consistency.
● Specific Rotation
The optical rotation of γ-CD is measured in aqueous solution using a polarimeter. The acceptable range of specific rotation is between +174° and +180°, confirming stereochemical purity and consistency with reference standards.
● PH Measurement
A saturated potassium chloride solution is added to an aqueous γ-CD sample, and the pH is measured using a calibrated pH meter. The expected range is 5.0 to 8.0, indicating appropriate chemical stability.
● Purity and Content Determination
Quantitative analysis of γ-CD is performed by HPLC using an octadecylsilane-bonded silica column and a water–methanol mobile phase. The concentration is determined using the external standard method to ensure accurate purity assessment.
● Reducing Sugar Content
An alkaline copper tartrate solution is added to the γ-CD sample and boiled. The solution is then titrated with potassium permanganate while hot. The titrant volume reflects the level of reducing sugars present in the product.
● Moisture and Residue Analysis
Samples are dried at 105°C to constant weight to determine loss on drying, which should not exceed 11 percent. The residue remaining after complete incineration must be less than 0.1 percent, ensuring minimal inorganic impurities.
● Heavy Metal Analysis
Trace metal and arsenic contents are determined using inductively coupled plasma mass spectrometry (ICP-MS). This method provides highly sensitive and accurate quantification of heavy metals, ensuring γ-CD complies with pharmacopeial safety limits.
● Microbial Limit Testing
Microbial enumeration methods are performed to assess total aerobic bacterial counts, yeasts, and molds. The acceptable limits are less than 10³ CFU/g for aerobic bacteria and less than 10² CFU/g for yeasts and molds. Escherichia coli must not be present, confirming the microbiological safety of γ-CD for pharmaceutical and food-grade applications.
